hi,(adsbygoogle = window.adsbygoogle || []).push({});

the standard (?) explanation for particle exchange to produce

repulsion and attraction is at:

http://math.ucr.edu/home/baez/physics/Quantum/virtual_particles.html

this seems to me to have two problems.

1.) in the case of repulsion beteen two electrons,

the direction has to be fine tuned to contrive that the

absorbing electron gets hit by the photon.

the probability of that happening is zero.

(the probability of a straight line eminating from a

point hitting some other random point in 3-d space is zero)

2.) asymetry in that one electron is an emitter and one

is an absorber.

3.) attraction requires quite a bit of hand waving for such a

fundamental response (and also still requires a special fine tuning)

how about this for an alternative:

each particle emits virtual photons in all directions

(i am thinking sin waves in this example)

two electrons intereract because everything cancels out except

for the wave between them

..|...|..

-(e)=(e)- net effect: (e)=(e)

..|...|..

the net affect is a photon exchanged between them and repulsion

aka the usual feynman diagram >-<

electron and a positive charge interact similary, but because

of opposite charge

..|...|..

-(e)0(p)- net effect: -(e)0(p)-

..|...|..

the interior photon cancels to zero

leaving a net attraction

net efect is a feynman diagram -< >-

its kind of like a casimir effect.

for charge/EM the photon is like cos(q*wt + phi)

with phi the angle of emmission.

looking along the x-axis

for two charges q1 and q2

to the left

left=cos(q1 wt + pi ) + cos(q2 wt + pi)

in the middle

middle=cos(q1 wt + 0) + cos(q2 wt + pi)

to the right

right=cos(q1 wt + 0) + cos(q2 wt + 0)

if(q1 == q2) {

then left=0; right=0;

and there is an exchange of

photons in the middle = repulsion}

if(q1 == -q2){

then left=-2cos(qwt);right=2cos(qwt);

middle=0;

=attraction

}

even more speculative, if you say the phase of the

photon is somehow a property of the spin , this could

also explain why gravity is always attractive

what do you think? crazy? already done?

i should go back to work?
